Jumbo Gardens, Ontariens` .Canada Application `January 23, 1948Se17ia1 1510.3,934- f 1 claim. (orme-e) This invention relates to. fruit juice extractors and strainers used for removing juice and pulp vfrom the halves of citrus fruits, such as oranges,

lemons, grapefruit, and the like, and in particular a fruit juicer having a fiuted conical-shaped operate with an oscillating or escapement actionV and being spring activated' produces a violent action with a sudden stop. This action of the strainer is independent of and unrelated to the speed of the reamer, and is not controlled by the operator.

The object of this invention is to provide a fruit juicer having a uted reamer for removing the Juice andpulpzfrom the fruit and a strainer wherein the parts are actuated with different movements by a common handle.

Another object of the invention is to provide means for operating a strainer of a fruit juicer having a reamer Vwith a relatively quick snappy or jerky action.

Another object of the invention is to provide a manually actuated fruit juicer in which the operating power is applied at a relatively low elevation in the device in order to prevent overturning oi' the juicer in use.

A further object of the invention is to provide an efficient manually actuated juicer for citrus fruits and the like which includes a reamer and a strainer with each operating with different movements, which is of a simple and economical construction.

'y Q fWith these and other objectsl and advantages in view the invention consistsiof the 'new' and novel combination, construction, and arrangement of parts as hereinafter more fully described, set forth in the claims appended hereto. and disclosed in the accompanying drawings forming part hereof, wherein:

Referring now to the drawings wherein like reference characters indicate corresponding parts the fruit juice4 extractor and Vstrainer of this invention include a 'housing I0, avreamer II, a strainer` I2, a'shaft I3, and a handle I4.

The` housing YIllisprovided with a base flange is provided for actuatiland a horizontally 'disposed partition I6 with a downwardly"extending sleeveH forming a bearing for the shaft I 3, andthe upper end of the housing is provided with a cover Yplate' I8 that is held in position by screws I9.

The reamer l l is formed with ridges 20 and grooves 2| forming flutes in the surface and the iouter part is mounted on a sleeve 22 having a end 28 of the handle is rotatably mounted in bearings 29 and 3U of the housing and the segment 21 is fixedly mounted thereon by a set screw 3l. The hub of the gear 26 is also provided with a set screw 32 by which it is held on the shaft I3, and the outer end of the handle is provided with a knob 33.

The strainer `l2 is providedwith a bushing 34 having an annular recess 35 in which the strainer is held and the lower end of the bushingis formed with key slots 36 into which the upper ends of keys 31 and 38 extend andthe keys-are integral with an actuator 39 having a hub 4l l1a i 'i d an arm 4l with a slot 42 therein. The actuator is freely mounted on the shaft'l3 and the upper end 43 of the crank 44, which is pivotally mounted in an opening 45 of the partition lr6, vextends `into the slot 42, and is resiliently held inward by a spring 46. The spring 46 is positioned on a hub or wheel 41 that is xedly mounted on the shaft I3 through 'a 'set screw ..49 andi the hub is provided with spaced'teeth 49fbetii'reenwhich the lend 4 3 of the crank is held by the spring*46.t1t will be noted, particularly in'Figu-re 5, 4that as the shaft I3 is rotated in eithe'ra clockwise or'coun-I terclock-wise direction theupper end=43 .of the crank 44, thelowerendlbeing pivoted in the -opening 45, will travel outwad'irithe s1ot142 of the actuator 39, moving the strainer 'slowly :in

vthesame direction oirotation as that of the Yream'eruntil -thefupper Vendridestof of'one of the teeth'49 of the hub 41,'arid as the end 'of the 1` crank rides offfof the toothi'the 'spring-4'6"l will snap the end of the crank backward therebyfre- --turning the' strainer with aquick snappy movement, providing a'n oscillating f .strainer with a reciprocating reamer. The comparatively'close 'spacing of theteetli'causes the fs'trainer tomove forward and snap backward a plurality ofitimes las the operating crankisimoved from'. one. po-

sition to another.

The strainer `l2 .isprovided with a peripheral flange .5B-and' Vthe .surface ofzthe strainer is `.formed with .perforationsfor' openings4 5|v the t edges of which. are curved upwardly as shownin .Figure 11, providing cutting edges 52. Withk the strainer formed in this manner the 'pulp of the wfruitE is subjected to agrating action which is :accentuated by the quickrsna'ppy movement of the strainer, which when released, is snapped .against a stop. As the juice is removed itpassesthrough Vthe H'strainer into the tray 53 from'whichit may flow through a spout 54 into a container. j

A...In the design shown .in VFigures 13"to"16 the 1' .deviceis formed with'a`housing156, similar Vto .the .housing.lzandagreamer 51 is`mounted on a .shaft ,58.and operated .by a drank 59 through gears 60 andll. Thelower endiv62 of the'crank .is .journaled bearings n63 and 164 .off the housing and .a 'cam' 65 withjteeth 66", thereon is mountedontheerd 62.? n'thisdesighc'asleeve 1 .61 is freely .mounted on tlieshaft 58 vand Ythe upper end ofthesieeve is formed with keys 68 and 69, similar to the keys 31 and 38 of the actuator 39, which extend into recesses 10 of a bushing 1l similar to the bushing 34. The strainer 12 is mounted in the bushing 1| and positioned in a tray 13 below the reamer 51.

The lower end of the sleeve 61 is provided with an arm 14 that extends downward with the lower f end thereof-positioned' to" engage the teeth 65 of vthe cam 65,and asl thecam" rotates the teeth thereof will push the arm 14 toward either side rotating the sleeve 61 and thereby actuating the strainer. The arm, sleeve, and strainer are refturned by a spring 15, one end of which is attached to a projection 16 on the arm and the f-otherto a' collar 11 which is freely mounted on the end 62 of the crank. VWiththe partsA arranged in this manner onehalf of an orange or the like may be held on the -reamer and the reamer and strainer may be actuated, as described, by moving the handle I4 `-forward andbackwardby. hand.
